Maintenance
lThe projector requires very little maintenance. You should keep the lens clean because any dirt or stains may
appear on the screen. Clean the air filter attached to the bottom of the projector periodically because a
clogged air filter prevents proper ventilation which is necessary to cool the projector and prevents it from over-
heating. If any parts need to be replaced, contact your service center.
l When cleaning any part of the projector, always turn the power off and unplug the projector first.
Cleaning the lens Cleaning the lens
Clean the lens if dirt or dust appears on the surface of it. Wipe the lens surface gently with a soft, dry lint-free
cloth, or use an air spray.
To remove dirt or stains on the lens, moisten a soft cloth with water and a mild detergent and wipe the lens  
surface gently. 
Cleaning the Projector Case Cleaning the Projector Case
To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth. To remove stubborn dirt or stains, moisten
a soft cloth with water and a mild detergent and then wipe the case.
Do not use alcohol, benzene, thinners or other chemical detergents as these can cause damage to the case.
Cleaning the  Cleaning the 
Air Filter Air Filter
The air filter, which is located on the bottom of the projector, should be cleaned after every 100 hours of use. 
If it is not cleaned periodically, it can become clogged with dust and prevent the projector from being ventilat-
ed properly. This may cause overheating and damage of the projector.
To clean the air filter :
1. Stand the projector on its side  so that the handle is on the top, so you can easily access the air filter.
2. Push the opening tip of the air filter cover and remove the cover.
3. To clean the filter, use a small vacuum cleaner designed for computers or other office equipment. Or you
may use a dry, lint-free cloth.
If it is difficult to remove dirt or if the filter is torn, contact your service center for replacement.
5. Close the filter cover after cleaning.
